1. Make sure all protective devices are properly installedincluding non-metallic handles and compartment coverswhen installing or re-installing the chassis or chassisassemblies.

2. Make sure that no gaps exist between the cabinets forchildren to insert their fingers in to prevent children fromreceiving electric shocks. Gaps mentioned above includeventilation holes between the PDP module and the cabi-net mask, and the improper installation of the rear cabi-net.

Errors may occur when the resistance is below 1.0 ㏁ orover 5.2 ㏁.In these cases, make sure that the device is repairedbefore sending it back to the customer.

3. Check for Electricity Leakage (Figure 1-1)Warning: Do not use an insulated transformer for check-ing the leakage. Use only those current leakage testersor mirroring systems that comply with ANSIC 101.1 andthe Underwriter Laboratory's specifications (UL1410,59.7).

Fig. 1-1 AC Leakage Test

4. A high voltage is maintained within the specified limitsusing safety parts, calibration and tolerances. When voltage exceeds the specified limits, check each specialpart.

5. Warning for Engineering Changes:Never make any changes or additions to the circuitdesign or the internal part for this product.Ex: Do not add any audio or video accessoryconnectors. This might cause physical damage.Furthermore, any changes or additions to the originaldesign/engineering will invalidate the warranty.

6. Warning - Hot Chassis:Some TV chassis are directly connected to one end ofthe AC power cord for electrical reasons.Without insulated transformers, the product can only berepaired safely when the chassis is connected to theearth end of the AC power source.

To make sure the AC power cord is properly connected,follow the instructions below. Use the voltmeter tomeasure the voltage between the chassis and theearth ground. If the measurement is over 1.0V, unplugthe AC power cord and change the polarity before re-inserting it. Measure the voltage between the chassisand the ground again.

7. Some TV chassis are shipped with an additional sec-ondary grounding system. The secondary system isadjacent to the AC power line. These two groundingsystems are separated in the circuit using an unbreak-able/unchangeable insulation material.

8. When any parts, material or wiring appear overheated ordamaged, replace them with new immediately. Whenany damage or overheating is detected, correct thisimmediately and make a regular check of possibleerrors.

9. Check for the original shape of the lead, especially thatof the antenna wiring, any sharp edges, the AC powerand the high voltage power. Carefully check if the wiringis too tight, incorrectly placed or loose. Never change thespace between the part and the printed circuit board.Check the AC power cord for possible damages. Keepthe part or the lead away from any heat-emittingmaterials.

10. Safety Indication:Some electrical circuits or device related materialsrequire special attention to their safety features, whichcannot be viewed by the naked eye. If an original part isreplaced with another irregular one, the safety orprotective features will be lost even if the new one has ahigher voltage or more watts.

Critical safety parts should be bracketed with ( ).Use only regular parts for replacements (in particular,flame resistance and dielectric strength specifications).Irregular parts or materials may cause electric shock orfire.

Precaution

!

1. The service instructions are printed on the cabinet, andshould be followed by any service personnel.

2. Make sure to unplug the AC power cord from the powersource before starting any repairs.(a) Remove or re-install parts or assemblies.(b) Disconnect the electric plug or connector, if any.(c) Connect the test part in parallel with the electrolyticcapacitor.

3. Some parts are placed at a higher position than theprinted board. Insulated tubes or tapes are used for thispurpose. The internal wiring is clamped using buckles toavoid contact with heat emitting parts. These parts areinstalled back to their original position.

4. After the repair, make sure to check if the screws, partsor cables are properly installed. Make sure no damage iscaused to the repaired part and its surroundings.

5. Check for insulation between the blade of the AC plugand that of any conductive materials (i.e. the metalpanel, input terminal, earphone jack, etc).

6. Insulation Check Process: Unplug the power cord fromthe AC source and turn the switch on. Connect the insu-lating resistance meter (500v) to the AC plug blade.

The insulating resistance between the blade of the ACplug and that of the conductive material should be morethan 1 ㏁.

7. Any B+ interlock should not be damaged.If the metal heat sink is not properly installed, noconnection to the AC power should be made.

8. Make sure the grounding lead of the tester is connectedto the chassis ground before connecting to the positivelead. The ground lead of the tester should be removedlast.

9. Beware of risks of any current leakage coming intocontact with the high-capacity capacitor.

10. The sharp edges of the metal material may causephysical damage, so protect yourself by wearing glovesduring the repair.

11. Due to the nature of plasma display panels, partial after-images may appear if a still picture is displayed on thescreen for a long period of time.This is caused by brightness deterioration due to thestorage effect of the panel, and to prevent this fromhappening, we recommend that the brightness and con-trast are reduced.(e.g.) Contrast: 25, Brightness: 50

Precaution


Warning 1: First carefully read the "Safety Instruction" in this service manual.When there is a conflict between the service and the safety instructions, follow the safety instruction at all times.

Warning 2: Any electrolytic capacitor with the wrong polarity will explode.

1-2 Servicing Precautions

1-3 Static Electricity Precautions1. Some semi-conductive ("solid state") devices are

vulnerable to static electricity. These devices are knownas ESD. ESD includes the integrated circuit and the fieldeffect transistor. To avoid any materials damage fromelectrostatic shock, follow the instructions describedbelow.

2. Remove any static electricity from your body byconnecting the earth ground before handling anysemi-conductive parts or assemblies. Alternatively, wear a dischargeable wrist-belt.(Make sure to remove any static electricity beforeconnecting the power source - this is a safety instructionfor avoiding electric shock)

3. Remove the ESD assembly and place it on a conductivesurface such as aluminum foil to prevent accumulatingstatic electricity.

4. Do not use any Freon-based chemicals.Such chemicals will generate static electricity thatcauses damage to the ESD.

5. Use only grounded-tip irons for soldering purposes.

6. Use only anti-static solder removal devices.Most solder removal devices do not support ananti-static feature. A solder removal device without ananti-static feature can store enough static electricity tocause damage to the ESD.

7. Do not remove the ESD from the protective box until thereplacement is ready. Most ESD replacements arecovered with lead, which will cause a short to the entireunit due to the conductive foam, aluminum foil or otherconductive materials.

8. Remove the protective material from the ESDreplacement lead immediately after connecting it to thechassis or circuit assembly.

9. Take extreme caution in handling any uncovered ESDreplacements. Actions such as brushing clothes or liftingyour leg from the carpet floor can generate enough staticelectricity to damage the ESD.

Precaution


CAUTION

These servicing instructions are for use by qualified service personnel only. To reduce the risk of electric shock do not perform any servicing other than that contained in theoperating instructions unless you are qualified to do so.

Precaution


1-4 Installation Precautions1. For safety reasons, more than two people are required

for carrying the product.

2. Keep the power cord away from any heat emittingdevices, as a melted covering may cause fire or electricshock.

3. Do not place the product in areas with poor ventilationsuch as a bookshelf or closet. The increased internaltemperature may cause fire.

4. Bend the external antenna cable when connecting it tothe product. This is a measure to protect it from beingexposed to moisture. Otherwise, it may cause a fire orelectric shock.

5. Make sure to turn the power off and unplug the powercord from the outlet before repositioning the product.Also check the antenna cable or the external connectorsif they are fully unplugged. Damage to the cord maycause fire or electric shock.

6. Keep the antenna far away from any high-voltage cablesand install it firmly. Contact with the high-voltage cable orthe antenna falling over may cause fire or electric shock.

7. When connecting the RF antenna, check for a DTVreceiving system and install a separate DTV receptionantenna for areas with no DTV signal.

8. When installing the product, leave enough space (4")between the product and the wall for ventilationpurposes.A rise in temperature within the product may cause fire.

9. When moving a PDP with removable speakers, detachthe speakers first before moving the main body.Moving the PDP main body without separating thespeakers may cause the speakers to detach, possiblycausing damage or injury.

■ SMPS BoardThe SMPS used for the PDP has been designed to be efficient, compact and lightweight. For VS and VA outputs, a LLC converterhas been used. For the other outputs, a Flyback converter has been used.

■ LOGIC BoardThe logic circuit consists of a Logic Main Board and an Address Buffer Board. The Logic Main Board decodes the video signalencoded by the Video Board, outputs the ADDRESS data signal for each pattern and generates X and Y drive signals. TheAddress Buffer Board buffers and transfers the ADDRESS data output signal using TCP IC.

- LVDS with built-in video signal processing (W/L, error diffusion, APC, FCR, etc.) applied and 1 ASIC chip.- Outputs the address Drive IC control and data signals to the Buffer Board.- Outputs the control signal for the X and Y Drive Boards.- Monitors major drive voltages (Micom Circuit Block); detects if a surge voltage has been applied and protects the Drive Circuit.- Temperature Adaptive Operating Mode (Low Temperature/Room Temperature/High Temperature); Discharge optimization for

each temperature level.

■ X-MAIN BoardConnects to the X terminal block, 1) provides maintaining voltage waveform (including ERC), and 2) maintains the Ve bias in theScan section.

■ Y-MAIN BoardConnects to the Y terminal block, 1) provides maintaining voltage waveform (including ERC), 2) provides Y Rising, Falling Rampwaveforms, and 3) maintains the Vscan bias.
